You can identify the authenticity of diamonds by observing the inside, dripping water, lighting and other methods. Natural diamonds are transparent inside, some are accompanied by mineral inclusions, and fake diamonds have many bubbles of impurities. After the natural diamond drops, the water drops expand for a long time, and the fake diamond will soon disperse. When light shines on natural diamonds, it will reflect shining brilliance, while the brilliance reflected by fake diamonds is very vague.

1, observe the internal method.

When identifying the authenticity of diamonds, we can distinguish them by observing the inside with a magnifying glass. Generally, natural diamonds are relatively transparent, and some are accompanied by mineral inclusions, growth structures and other inclusions, while fake diamonds are mainly bubbles.

2, dripping identification method

It can also be distinguished by dripping water. You can drop a few drops of water on the diamond. If the water drops last for a long time and don't scatter, it is genuine. If it disperses quickly, it may be fake diamonds.

3. Illumination method

Or through the method of light irradiation to identify, natural diamonds have high refractive index, and colorful fire colors can be seen through light or sunlight irradiation, while fake diamonds rarely have fire colors.
